Lache Seastrunk, James Sims, John Hubert, Brennan Clay and Charles Sims are gone. Last season, they combined for 24.8 percent of the Big 12’s 21,705 yards on the ground throughout the season. Here’s a look at the top 10 returning running backs in the conference for 2014.

10. Devin Chafin, So., Baylor

Devin Chafin was Baylor’s No. 4 option in the backfield last season. Injuries to Lache Seastrunk and Glasco Martin allowed Chafin to break out his freshman year for 295 rush yards last season.

9. Joe Bergeron, Sr., Texas

Joe Bergeron was part of UT’s major run attack last season. He finished the year with 362 rush yards and averaged a team-high five yards per carry.

8. DeAndre Washington, Jr., Texas Tech

DeAndre Washington was behind Kenny Williams last season, but with Williams moving to linebacker this season, Washington is poised to carry over his success from last year. He finished 2013 with 450 yards on the ground and four touchdowns.

7. Dreamius Smith, Sr.West Virginia

Dreamius Smith’s 494 rush yards last season pale in comparison to Charles Sims’ 1,095 yards. However, with Sims graduated, Smith has the ability to make a statement for the Mountaineers this year.

6. Aaron Wimberly, Sr.Iowa State

Aaron Wimberly led the Cyclones last season in rushing with 567 yards on the ground, 32.9 percent of Iowa State’s 1,726 rushing yards on the year. Wimberly finished with a pair of touchdowns in 2013.

5. B.J. Catalon, Jr., TCU

B.J. Catalon led the Horned Frogs in rushing last year with 569 total rushing yards and six touchdowns. While he averaged 5.3 yards per carry, he amounted for 39.9 percent TCU’s 1,423 total yards on the ground.

4. Johnathan Gray, Jr., Texas

Johnathan Gray was No. 2 for the Longhorns last year with 780 rushing yards and four touchdowns. He averaged 4.9 yards per carry in 159 attempts.

3. Desmond Roland, Sr.Oklahoma State

Desmond Roland was Oklahoma State’s main ground attack last season with a team-high 811 rushing yards. He also scored 13 touchdowns while counting for 36.3 percent of OSU’s total 2,235 yards on the ground.

2. Shock Linwood, So., Baylor

Shock Linwood broke out after Lache Seastrunk and Glasco Martin went down with injuries. He ended up No. 2 for Baylor on the ground with 894 yards for 26.1 of the Bears’ 3,376 rush yards. Linwood scored eight touchdowns while gaining 6.9 yards per carry.

1. Malcolm Brown, Sr., Texas

Malcolm Brown led the UT rushers last season with 904 yards on the ground and nine touchdowns. Alone he made up 35.4 percent of Texas’ 2,551 total rushing yards. With Johnathan Gray and Joe Bergeron, the trio counted for 80.2 of the Longhorns’ rush attack.
